Biochem/physiol Actions

BAY41-4109 is a heteroaryldihydropyrimidine (HAP)-based capsid assembly modulator (CAM) that destabilizes hepatitis B virus (HBV) capsid assembly. BAY41-4109 inhibits HBV replication in HepG2.2.15 cultures with little host cytotoxicity (IC50 = 53 nM vs. CC50 = 7 μM in 8 days). Despite its relatively short half-life in vivo (plasma t1/2 = 5 h/dog, 2 h/rat, ≤1 h/mouse), BAY41-4109 shows greater antiviral efficacy than 3TC in Tg [HBV1.3 fsX-3′5′] mice (HBV DNA reduction = 52%/BAY vs. 36%/3TC in liver via 30 mg/kg b.i.d. p.o.; 70% vs. 30% in plasma with 15 mg BAY/kg or 30 mg/kg 3TC b.i.d. p.o., respectively) with good oral availability (F/tmax =31%/mouse, 58%/rat & dog).

Chronic hepatitis B virus (HBV) infection is a major cause of liver disease. Only interferon-alpha and the nucleosidic inhibitors of the viral polymerase, 3TC and adefovir, are approved for therapy. However, these therapies are limited by the side effects of

Hepatitis B virus (HBV) core protein assembles viral pre-genomic (pg) RNA and DNA polymerase into nucleocapsids for reverse transcriptional DNA replication to take place. Several chemotypes of small molecules, including heteroaryldihydropyrimidines (HAPs) and sulfamoylbenzamides (SBAs), have been discovered to allosterically

Hepatitis B virus (HBV)-associated chronic liver diseases are treated with nucleoside analogs that target the virus polymerase. While these analogs are potent, drugs are needed to target other virus-encoded gene products to better block the virus replication cycle and chronic

Here we report the effect of a heteroaryldihydropyrimidine (HAP) antiviral compound, BAY 41-4109, on Hepatitis B virus (HBV) capsid assembly and on preformed HBV capsids. The HBV capsid is an icosahedral complex of 120 capsid protein dimers. BAY41-4109 inhibits virus

BAY 41-4109 is a member of a class of heteroaryl-pyrimidines that was recently identified as potent inhibitors of human hepatitis B virus (HBV) replication. We have investigated the antiviral activity of BAY 41-4109 (methyl (R)-4-(2-chloro-4-fluorophenyl)-2-(3,5-difluoro-2-pyridinyl)-6-methyl-1,4-dihydro-pyrimidine-5-carboxylate) in HBV-transgenic mice (Tg [HBV1.3
